SHOE-POLISHING MACHINERY.

Application filed. January .22, 1917.

To all whom it may concern Be it known that 1, PETER J. RUMPF, citizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented a certain new and useful Improvement inShoe-Polishing Machinery, of which the following is a full, clear,concise, and exact description.

This invention relates to improvements in shoe machinery and moreparticularly to shoe polishing machinery.

In the manufacture of boots and shoes as now commonly carried on, it iscustomary to apply to the soles thereof, a suitable polish commonlyknown as bottom polish which is generally in the form of a speciallyprepared wax and which is designed to fill up the crevices andinterstices in the leather, to render the same more or less imperviousto water, and to impart a polish thereto. Heretofore in actual practiceit has been common to apply the polish to the polishing element by hand,the polish in the form of a cake, being pressed against the polishingelement, which is generally in the form of a rotary brush, so that aportion of the same is taken up by said brush; the cake of polish beingthen laid aside and the sole of a shoe held against the brush to therebytreat and polish the same. This procedure is slow and cumbersome andalso very wasteful of the material used, by reason of the fact that whena cake of the same becomes too short to permit of the same beingconveniently handled, it is thrown away and a new cake substituted.

The present invention aims to overcome these various disadvantages, andhas for its object the provision of a machine wherein the polish is fedinto contact with the brushing element automatically; another objectbeing to provide means whereby the speed of the automatic feedingmechanism may be varied as desired to increase or decrease the feedingoperation.

A further object of the invention is to provide a machine of the typedescribed with a novel form of holder, adapted to receive the polish andto cooperate with the feeding mechanism, whereby said polish is fedupwardly into contact with the polishing element.

Other objects will be apparent from the fOllOWiIlg description, taken inconnection with the accompanying drawings, in which is shown thepreferred embodiment of my Specification of Letters Patent.

invent-ion. It is to be understood however, that the disclosure is forpurposes of illustration only, the same being susceptible of manychanges and modifications, and the right is herein reserved to make suchchanges as fairly fall within the scope of the appended claims.

Figure 1 is a side elevation of the ma-- chine, the brushing element andmain shaft being shown partly broken away.

Fig. 2 is a front elevation thereof.

Fig. 3 is a detailed sectional view of one of the guides.

Fig. 1 is an enlarged fragmentary view partly in section, of a portionof the ma" chine;

Fig. 5 is an enlarged side elevation of the eccentric mechanism; and

Fig. 6 is a transverse sectional view thereof.

Fig. 7 is a sectional detail on line 77, Fig. 3.

In the drawings, the base of the machine is illustrated at 10 and isshown provided with suitable flanges 11 adapted to receive bolts orother fastening means (not shown), whereby said base may be secured to asuitable support 12, shown in dotted lines in Figs. 1 and 2. Pivotallymounted at 13 on the base 10, by means of suitable lugs 1-1, preferablyintegral therewith, is a wax or polish holder 15. At 16 is pivoted asuitable lock adapted to swing into and out of engagement with theflange 17 of the holder 15 to fasten the same in its closed position onthe base 10, as shown in Fig. 2. This looking mechanism is shownprovided with a suitable set screw 18 which may be screwed down intocontact with the flange 17 to retain the wax holder against accidentaldisplacement. The holder 15 may be cast iiitegral if desired, but isshown in the drawings as provided with an inner cylindrical sleeve 15,within which the cake of wax" or polish is placed.

Depending from the base 10 is a suitable frame 19 adapted to support theoperating mechanism of the machine. This frame 19 comprises dependingside members 20, a transverse member 21, hangers 22, and a suitablebracket 23, all of which may be cast integral .if desired, they beingshown in the drawings however, as formed separately and secured togetherby suitable fastening means. Mounted on the hangers 22 is a countershaft 21, on one end of which is shown a pulley adapted to be driven bymeans of a suitable belt 26 from the main shaft 27. Mounted transverselyof the side members 20 of the frame 19, are a plurality of shafts 28 and29, the latter of which is shown provided with a gear wheel 30 whichmeshes with the worm 31 formed on the counter shaft 2i. Mounted on oneend of the shaft 29 is an eccentric 32 provided with suitable pawl 33adapted for engagement with a ratchet wheel 3-l mounted on thecorresponding end of the shaft 28. Intermediate the ends of the shaft 28is shown a pinion 35 meshing with a rack 36 which is shown mounted insuitable guides 37 and 38. The rack 36 as shown, extends through thebase 10 in such a manner as to lie substantially in the center of thewax holder 15, said rack 36 being provided at its upper end with a waxsupporting base 39, adapted to reciprocate within the cylindrical sleeve15 of the holder 15 in a manner hereinafter described. The base 39 maybe integral with said rack but is shown in the drawings as securedthereto by a set screw 40. The bracket 23 is bolted to the side members20 of the frame 19 and depends therefrom. Positioned in the lower end ofsaid bracket is a suitable cup n adapted to cushion the rack 36 when thesame is released as hereinafter set forth. This cup may be provided withfelt or other suitable cushioning material.

The pawl 33 working in conjunction with the eccentric 32 and the ratchetwheel 3i preferably passes through a suitable guide T2, said guide beingprovided with an up turned flange *3 and secured in any suitable mannerto the frame 19 adjacent said ratchet wheel 34:. A spring 5%, connectedto the upturned flange as of the guide 12 at one end and to the pawl 33at the other end, provides means whereby said pawl is held in positiveengagement with the teeth of the ratchet wheel 3i.

Pivotally mounted directly beneath the base 10 between lugs is a lever&6, one end of which is connected to the pawl 33 by means of a suitableconnecting member 4L7, shown in the drawings in the form of a wire. Asuitable set screw as is shown screw-threaded in the base 10, and isadapt ed to bear on the other end of said lever &6, whereby the pawl 33may be raised out of engagement with the ratchet wheel 3% against theaction of the spring i4, when the pressure of said set screw 48 isincreased. The spring 44 returns the pawl 33 into engagement with theratchet wheel 3& when the pressure of said screw 48 is released. Pivotedat 49 to one of the side members 20 of the frame 19, is shown a dog 50which is adapted to engage the teeth of the ratchet wheel 34 to preventany reverse movement of said ratchet wheel while the pawl 33 is beingcarried back by the eccentric 32 prior to its forward movement. A spring51 keeps the dog 50 in engagement with the teeth of the wheel Suitableadjustable means is shown extending upwardly through the base 10 fromone end of the dog 50, whereby said dog may be drawn out of engagementwith the ratchet wheel 33, for purposes hereinafter set forth.

In Figs. 5 and 6, the eccentric 32 is shown more in detail. From thesefigures it will be noted that the throw of the eccentric may be varied,whereby the feeding upward of the rack 36 by virtue of the cooperationbetween the pawl 33, ratchet wheel 34c, and pinion 35, may be increasedor decreased as desired. As shown, the eccentric 32 is provided with aslotted member 53, swaged or otherwise secured directly on the end ofthe transverse shaft 29 and adapted to revolve therewith. Secured to theouter circumference of the member 53, is a substantially semi-circularring 5%, shown slotted at 55 for the reception of a suitable adjustingscrew 56, which lies within the slot in said member 53, and which isheld against reciprocatory movements therein by means of the collars 57which engage opposite sides of the ring 5% as shown. The screw 56engages a suitable studded block 58 also mounted within the slot of themember said block 58 being adapted to be reciprocated therein by theturning of the screw 56 to thereby increase or decrease the eccentricposition of the same. A nut 59 is mounted on the outer end of the stud,which is preferably integral with the block 58, for the purpose ofclamping the various parts in any desired relation. Pivotally mounted onsaid stud intermediate said block and the nut 59, is the pawl 33. Itwill be noted from this structure that the step by step movementimparted to the shaft 28 by means of the pawl and ratchet mechanism, maybe varied without reducing the speed of the shaft 29. r

In the operation of the machine, the pawl 33 and the dog 50 are drawnout of engage ment with the ratchet wheel 34, thus permit-- ting therack 36 to descend until the rear end thereof engages the cup i1. W henthe rack is in this position, the supporting base 39 lies at the bottomof the wax holder 15, and in contact with the base 10. This permits thewax holder 15 after the same has been released by swinging the lock 16out of engagement with the flange 17 thereof, to be swung back on itspivot 13 to the dotted line position as shown in Fig. 2. A cake of waxor other polishing *material, is then inserted into the cylindricalsleeve 15 of said holder 15, preferably from the rear thereof, saidholder being then swung back into its operative position on the base 10and locked against accidental displacement. It will be noted from theforegoing that the wax,

which is illustrated at 60, will rest upon the supporting base 39,mounted on the upper end of the rack 36, when the holder has beenreturned to its operative position as flllJOVC described. The innercylindrical sleeve 15 of the holder 15 is preferably of such height thatthe cake of wax or other polish, when placed within the same willproject a short distance above the upper end thereof, and into contactwith the rotary brush (51 which is shown mounted on the main shaft 27,substantially as shown in Figs. 1 and The manner in which the step bystep upward movement of the rack 36 is accomplished, whereby the wax iskept in con-tact with the brush (31, will now be described.

Assuming that the parts are in the position shown in Figs. 1 and 2,motion is imparted to the pulley from the main shaft 2'? by means of thebelt 26. This revolves the counter shaft Ql and also the shaft 29 byvirtue of the gear wheel 30 and the worm 31. The pulley 25 is preferablymade many times larger in circumference than the shaft 2? in order thatthe counter shaft 2% will be driven at a reduced rate of speed. Therotary motion of the shaft 29 drives the eccentric 32, the pawl 33 ofwhich revolves the shaft 28 in the direction of the arrow in Fig. l, thedog 50 cooperating therewith to prevent any reverse rotation of saidshaft as heretofore pointed out. This step by step movement imparted tothe shaft 28 is transmitted by means of the pinion 35 to the rack 36,thus moving said rack upward. The cake of wax or other polishingmaterial, being mounted on the base 39, is likewise fed up 'ard by themovement of the rack 36 and accordingly is kept in contact with therotary brushing element 61. Should it be desired to stop the feedingoperation at any time, the pawl 33 may be raised out of contact with theratchet wheel 34:, as heretofore pointed out, the dog acting to hold therack in whatever position it is in at the time the withdrawal of thepawl 33 is effected. lVith the device as illustrated, it will be notedthat substantially the entire cake of wax or other polishing material isutilized, thus dispensing with the waste which exists in the methods nowin common use, as heretofore pointed out.

It is obvious that various changes may be made in the detailedconstruction of the machine, without departing from the spirit of theinvention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is 1. A machine of theclass described, comprising a table, a vertically-disposed wax holdernormally resting on said table, a rod extending upwardly into saidholder through an opening in said table and being provided with asupporting plate at its upper end, means coac-ting with the lower end ofsaid rod for feeding said plate upwardly, and means whereby said holdermay be tilted back out of engagement with said table to thereby renderaccess to said plate unobstrueted.
